Hello, I have an issue with my rocks not staying together/shifting. The tank is currently set up and i've tried over and over to get a sturdy base and rockscape. My question is, can I take dry rock such as BRS reefsaver, build it on the floor, cement it all together and then take my current live rock, put it into my refugium section [all flow goes through the refugium] and put the new aquascaped rocks into the tank? Would rinsing/soaking in RODI for a few days [or a week] be enough on reefsaver (there isn't supposed to be anything in/on it) to avoid problems with ammonia spikes/nitrate/phosphate? Is there any issue with moving all of the current bio-filtration [live rock] to the refugium section of my sump? I have fairly high flow coming from my overflows to my sump, but the water goes "over" the baffle from the refugium. Would the rock on the bottom possibly not get enough flow to maintain the bacteria? Any insight/info would be great! Also, if anyone's used the reefsaver BRS dry rock, and can comment on any smell/issues you had that would be very helpful as well!
